Characterisation Method Information
Characterisation Method Name:
SO2 impact on morbidity
Version:
1999
Date Completed:
1999
Principal Method Name:
EPS: secondary aerosol pathway
Method Description:
Model

The characterisation factor is determined by an equivalency method using PM10 as a reference.

Equivalency factor

The same equivalency factor is used as in "SO2 impact on severe morbidity" i.e. 2.83 kg ‘effective’ PM10/kg SO2.

Calculation of characterisation factor

According to "PM10 impact on morbidity" there are 3.61E-06 person-years of morbidity/kg PM10. We thus obtain
3.61E-06 *2.83 = 1.02E-05 person-years of morbidity per kg of SO2.
